But...don't you share that joint? So, 2 people = 2.5 cigarettes, and more people, even less. C'mon where's your sense of the social import? cough cough. Yeah, but the emphysema only occurred in cigarette smokers, wonder why. Also, remember today's pot has even higher THC than "ditch" weed from the 60's, so maybe only one or two hits will do.... Now, more math. One hit can't be more than 1/10th or 1/20th of a joint. Let's compromise at 1/15th. So now we're down to 1/3rd of a cigarette. And, if we don't smoke everyday, it's much less harmful then...but wait, it "causes" schizophrenia....so now we have to share it with "ourselves", as in "I'm a schizophrenic and so am I". Our other self gets another 1/3 of a cigarette, but it's still going into one person's lungs, so that's, ugh, let's see....2/3 of a cigarette. OK, so I suppose that's a little more serious.

OK, just stick with a Vapourizer. No, wait, I forgot...it can still "cause" schizophrenia. OK, my other half quits!!! I'll just sit at home and read more studies....and drink a cup of tea.
